Your Guide to a Leave From Work for Stress in Ontario

When the pressure of your job feels completely overwhelming, taking a step back isn’t just an option—it’s often a necessity. If you’re feeling burnt out, remember that in Ontario, taking a leave from work for stress is a protected right, not a personal failing. With the right medical support, you can get the time you need to recover without worrying about your job security.

Your Right to a Stress Leave Is Protected by Law

It’s a common fear among employees across the GTA and Ontario: will asking for a stress leave get me fired? The short answer is no. Provincial laws and most company benefit plans recognize that severe stress, anxiety, depression, and burnout are legitimate medical conditions that warrant time off.

Think of it this way: your rights are shielded by several layers of protection. The single most important thing to know is that your employer can’t simply dismiss a medically supported request for leave.

The Different Paths for Taking a Stress Leave

When you need time off for your mental health, you have more than one route you can take. Your specific situation will determine which path—or combination of paths—is right for you.

• Employer-Provided Sick Days: For a shorter break, your company’s paid sick day policy is your first line of defence. These can often be used for mental health days.
• Disability Benefits: Most group insurance plans offer Short-Term Disability (STD) and Long-Term Disability (LTD). These are designed to replace a portion of your income if you need to be off work for a prolonged period.
• Government Programs: If your employer doesn’t offer disability benefits, you may be eligible for Employment Insurance (EI) Sickness Benefits for financial support.
• Job-Protected Leave: Under Ontario’s Employment Standards Act, 2000 (ESA), you’re entitled to unpaid, job-protected sick leave for more serious medical issues.

The Ontario Human Rights Code is your strongest protection. It legally requires employers to accommodate employees with disabilities—and this absolutely includes mental health conditions. A medically necessary leave is a form of accommodation, and your employer has a duty to support it unless it causes them undue hardship.

Taking a stress leave is often a crucial part of recovering from burnout. This science-backed guide on how to recover from burnout offers some excellent strategies for the healing process.

Ultimately, your ability to take a leave from work for stress rests on getting clear support from your doctor or another healthcare provider. A medical note confirming that you are unable to perform your duties is the key that unlocks these protections. It transforms your request from a simple ask into a medical necessity, protecting your job while you focus on getting better.

How to Document Your Need for a Stress Leave

When the pressure from work becomes completely overwhelming, simply telling your employer you “feel stressed” isn’t going to be enough to secure a leave. To get the time off you need, you have to show them—and potentially an insurance company—exactly how that stress is making it impossible for you to do your job.

Think of it less as complaining and more as building a case. You’re creating a clear, factual record that transforms a vague feeling of being burnt out into a documented medical issue that requires a real solution: time away to recover.

Pinpointing and Tracking Your Symptoms

Your first move should be to start keeping a detailed record. A log of specific incidents and symptoms is powerful; vague feelings are easily dismissed. This doesn’t have to be complicated—a simple daily journal or even a running note on your phone will work.

The key is to be specific. For each entry, note the date, the time, and any workplace events that seemed to trigger your symptoms. Most importantly, describe how you felt and how it impacted your ability to function.

Ask yourself these questions as you write:

• What’s the physical toll? Are you dealing with constant headaches, stomach problems, or a bone-deep fatigue that sleep doesn’t fix? Write it down.
• What about the mental impact? Note every instance of “brain fog,” memory trouble, intense anxiety, or an inability to focus on your work.
• How has your behaviour changed? Are you pulling away from coworkers? Snapping at your family? Avoiding tasks you used to handle easily? These are all symptoms.

A detailed symptom journal is your single most important piece of evidence. It’s what your doctor will rely on to justify your need for a leave, and it’s the proof an insurance company will demand when reviewing your claim.

This isn’t just about your personal situation; it’s a widespread problem. A recent Telus Health report found that 70% of Canadian employees say their productivity is lower because of their mental health, and 59% admit to feeling burnt out. Tracking your experience helps prove you’re part of this reality.

Talking to Your Doctor Effectively

Once you have a week or two of detailed notes, it’s time to see your family doctor or a mental health professional. Your goal here is to walk out with a medical note that clearly explains your limitations, not just a diagnosis. Professional support can be invaluable in this process; resources like Penticton counselling can provide the expert guidance needed to articulate your situation effectively.

When you speak with your doctor, use your journal. Be direct and connect your symptoms to your job duties. Instead of saying, “I’m just too stressed,” try: “As you can see from my notes, I’m having migraines three times a week and can’t concentrate long enough to analyse the financial reports my job requires.”

This is the language that doctors and, more importantly, insurers understand. They need to see evidence of your functional limitations—what you physically and mentally cannot do right now. A note that focuses on this is the key to getting a disability claim approved.

Alright, you’ve spoken with your doctor and have their support. That’s a critical first step. Now, the question becomes: what kind of leave should you actually take?

Navigating your leave options can feel like a maze, especially when you’re already feeling overwhelmed. In Ontario, there are several different paths you can take, and each one has its own set of rules, benefits, and timelines. Let’s break down the most common options so you can figure out what makes the most sense for your situation.

For many people I’ve worked with, the first place they look is their company’s benefits package. Most employers offer a certain number of paid sick days, and these are perfect for a short-term break to decompress and get your bearings.

But what if you need more than just a few days? That’s when we start talking about disability benefits.

Short-Term vs. Long-Term Disability

If your stress is severe enough to require an extended absence, your group insurance plan is the next piece of the puzzle. These plans typically offer two kinds of income support.

• Short-Term Disability (STD): This is usually your first stop for a longer leave. STD benefits generally cover you for 15 to 26 weeks and pay a percentage of your regular salary. It’s designed to bridge the gap while you focus on recovery.
• Long-Term Disability (LTD): If your condition doesn’t improve by the time your STD runs out, you’ll need to apply for LTD. These benefits are a crucial lifeline, potentially providing financial support all the way to age 65 if you remain unable to return to work.

The application process for both STD and LTD is paperwork-heavy. You, your doctor, and your employer will all need to fill out detailed forms. The key here is making sure your doctor’s notes clearly and specifically connect your stress symptoms to your inability to perform your job duties. Vague notes just won’t cut it.

Our firm has guided countless clients through this process. If you want to dive deeper, you can find more practical advice in our guide on long-term disability benefits.

This flowchart maps out the initial journey, from the moment you realize you’re too stressed to work, to getting the medical documentation you need to move forward.

As you can see, getting that professional medical assessment is the non-negotiable foundation for accessing any of these formal leave options.

To help you see how these different options stack up, here’s a quick comparison of the primary types of leave available for stress in Ontario.

Comparing Stress Leave Options in Ontario

Leave Type	Typical Duration	Pay Status	Source of Benefit
Sick Days	A few days per year	Usually paid	Employer
Short-Term Disability (STD)	15 to 26 weeks	Paid (percentage of salary)	Insurance Company
Long-Term Disability (LTD)	Until return to work or age 65	Paid (percentage of salary)	Insurance Company
ESA Protected Leave	Up to 28 weeks per year	Unpaid (job-protected)	Government Legislation
WSIB	Varies	Paid (percentage of earnings)	WSIB (Government Agency)

This table provides a high-level overview, but the specifics of your situation will always determine the best path forward.

Your Rights Under Ontario Law

Beyond what your company’s insurance policy offers, it’s important to remember that provincial laws provide a strong safety net.

Under the Ontario Human Rights Code, your employer has a legal duty to accommodate your medical needs. This absolutely includes providing a leave of absence if your doctor says it’s necessary. Let me be clear: it is illegal for your employer to fire you for taking a medically supported stress leave. That’s discrimination, plain and simple.

On top of that, Ontario’s Employment Standards Act, 2000 (ESA) gives you job-protected leave. As of late 2024, employees are entitled to up to three days of sick leave, up to three days of family responsibility leave, and up to two days of bereavement leave per calendar year. More significantly for extended absences, the ESA provides for up to 28 weeks of unpaid medical leave (formerly sick leave) per year. This is a game-changer for people dealing with severe stress, as it guarantees your job will be there for you when you’re ready to return, provided you have a doctor’s certificate.

One final point to consider. In very specific and rare situations, you might be able to file a claim with the Workplace Safety and Insurance Board (WSIB) for “chronic mental stress.” This only applies if the stress was caused by something exceptional, like workplace harassment or a traumatic event—not the usual pressures of deadlines or difficult colleagues. The bar for these claims is quite high.

How to Talk to Your Employer About Your Leave

Telling your boss you need to take a leave from work for stress is probably the part of this process you’re dreading the most. I get it. In my experience working with people from Burlington to across the GTA, the biggest fears are being judged, seen as weak, or even putting their job on the line.

The key is to keep the conversation professional, confidential, and focused only on what your employer legally needs to know.

You don’t have to share your specific diagnosis or any personal details about your mental health. Your privacy is protected. All you really need to communicate are three simple facts:

• You require a medical leave of absence.
• The date your leave will begin.
• The expected duration of your leave, based on your doctor’s recommendation.

Informing Your Manager and HR

My advice is always the same: put it in writing. An email is your best friend here because it creates a clear, dated record of your request. If you feel more comfortable talking to your manager in person first, that’s perfectly fine—but you should always follow up with an email to both your manager and HR.

Keep your message short and to the point. There’s no need for a long explanation. Here’s a simple script you can adapt:

“I’m writing to inform you that I will be taking a medical leave of absence, as recommended by my doctor. My last day in the office will be [Date], and I anticipate returning on or around [Date]. I will forward the required medical certificate to HR shortly and will be in touch if there are any changes to my return-to-work date.”

This approach is professional and gives them all the information they’re entitled to without oversharing. You’ve officially stated your need for leave and its expected timeframe, which is all that’s required of you.

It’s no secret that workplaces are pressure cookers right now. A recent ‘State of Safety’ report found that 42% of decision-makers saw a spike in mental health issues at their companies last year, often made worse by chronic understaffing. You can read more about these trends in the full 2025 report from Threads of Life. This context is exactly why setting firm, professional boundaries in your leave request is so critical.

Managing Your Disability Claim

Once you’ve notified your employer, your focus shifts to dealing with the insurance provider for your disability claim. You’ll soon get a package of forms—one for you, one for your employer, and one for your doctor.

Take your time filling out your portion. Be painstakingly accurate. Make sure your description of your job duties and the symptoms affecting you line up perfectly with what your doctor is reporting.

Expert Tip: Inconsistencies between your application and your doctor’s report are a huge red flag for insurers and one of the most common reasons I see for claims being denied.

After submitting your forms, the insurance company will assign you a case manager. This person is now your main point of contact. It’s important to remember that their job is to manage the claim for the insurance company, and that includes looking for reasons to question or deny it.

I always tell my clients to communicate with the case manager in writing whenever possible. If you do have a phone call, send a quick follow-up email summarizing what you discussed. This creates a paper trail. If they ask for more information, politely ask them to send that request in an email. This protects you from any “he said, she said” confusion down the road and ensures everything is clearly documented.

What to Do When Your Stress Leave Is Denied

Getting a denial letter from your insurance company after you’ve finally made the difficult decision to take a leave from work for stress can feel like a punch to the gut. It’s a moment that often brings on a wave of frustration and panic, but it is absolutely not the end of the road. You have rights, and you have options.

The very first thing to do is take a breath. It’s crucial to understand that denials are incredibly common, especially when it comes to mental health claims. Insurance companies have a playbook they often run, and knowing their tactics is the first step in fighting back.

Why Was Your Stress Leave Denied?

From my experience, stress and burnout claims are frequently denied for a few predictable reasons. One of the most common justifications is citing a “lack of objective evidence.” Unlike a broken bone, there’s no X-ray or blood test to definitively prove what you’re going through. Insurers can use this ambiguity to argue that your doctor’s reports are based only on what you’ve said, not on “objective” medical findings.

Another classic move is for the insurer to rely on the opinion of their own medical consultant. This is usually an in-house doctor who has never met you, spoken to you, or examined you. They’ll review your file from a desk hundreds of kilometres away and conclude that your condition isn’t severe enough to stop you from working. It’s a powerful tactic, but one that can often be challenged.

Most denial letters will point to one of these reasons:

• Insufficient medical evidence to back up your inability to work.
• The insurer’s doctor simply disagrees with your doctor’s professional opinion.
• Claims that you aren’t following an “appropriate” treatment plan.
• You missed a deadline or didn’t fill out a form to their exact specifications.

When your benefits are denied, you need to act. The clock on your appeal deadlines starts ticking the moment you receive that letter.

Your Immediate Next Steps

Think of a denial not as a final verdict, but as the start of a dispute. The actions you take right away can make or break your chances of getting that decision overturned.

First, and this is critical, do not let them pressure you into returning to work if your doctor says you are still unable. If you go back, the insurer will immediately argue that you must not have needed the benefits in the first place. Your health has to come first.

Second, get on the phone and request a complete copy of your claim file from the insurer. This file is a treasure trove of information, containing every document they have on you—your medical records, their internal notes, and most importantly, the reports from their medical consultants. This is the evidence you need to build your appeal.

You have a legal right to appeal the insurer’s decision. The denial letter will outline an internal appeal process, but be warned: appealing directly to the same company that just denied you often leads to the same outcome. While it’s often a necessary step before you can take legal action, you need to go into it with a clear strategy.

When to Call a Lawyer

Knowing when to bring in legal help is crucial. Certain moves by an insurance company are major red flags that should tell you it’s time to get professional advice immediately.

One of the biggest red flags is a request for you to attend an Independent Medical Examination (IME). Don’t let the name fool you; this examination is anything but independent. It’s an assessment by a doctor chosen and paid for by the insurance company, and their goal is often to find a reason to deny or terminate your claim.

Another warning sign is surveillance. If you have even a slight suspicion that the insurer has hired a private investigator to follow you, it’s a sign they are actively trying to build a case against you.

If your claim has been denied or cut off, your strongest move is to seek legal counsel. A lawyer can take over all communication with the insurer, navigate the complex appeal process, and build a powerful case to get your benefits back.

Frequently Asked Questions About Ontario Stress Leave

Deciding to take a stress leave is a big step, and it’s natural to have a lot of questions swirling around. We hear them every day from employees across Ontario, from Burlington to the broader GTA. Here are some straightforward answers to the most common concerns we encounter.

Can My Employer Fire Me for Taking a Stress Leave in Ontario?

This is often the number one fear, so let’s be clear: No, your employer cannot legally fire you for taking a medically supported stress leave.

Your job is protected by a couple of powerful pieces of legislation in Ontario: the Employment Standards Act, 2000 (ESA) and the Ontario Human Rights Code. The Code views mental health conditions—including severe stress, anxiety, and depression—as disabilities.

Because of this, firing you for taking a disability-related leave is considered discrimination, which is illegal. Your employer has a duty to accommodate your medical needs, and that includes honouring a legitimate leave. The only exception is if they can prove that doing so would cause them “undue hardship,” a very high legal standard to meet.

Do I Have to Tell My Boss the Details of My Mental Health Condition?

Absolutely not. Your specific diagnosis and the private details of your health are confidential. You should never feel pressured to share them with your manager or HR.

All you really need to do is provide enough information to confirm that your absence is medically necessary. A proper doctor’s note is the key here. It should simply state:

• That you are medically unable to perform your work duties.
• The expected duration of your leave.
• Your general limitations and restrictions (without naming your condition).

Forcing you to disclose a specific diagnosis can cross the line into harassment. If your employer is pushing for private medical information you’re not comfortable sharing, it might be time to get some legal advice. If you feel your human rights are being violated, you can learn more in our guide on how to file a human rights complaint.

What if My Company Doesn’t Offer Short-Term Disability?

It’s a common situation, but don’t worry—you still have options for income support and job protection if your employer doesn’t have a short-term disability (STD) plan.

Your first stop will likely be Employment Insurance (EI) Sickness Benefits. This is a federal program that provides financial assistance for up to 26 weeks while you’re unable to work. You’ll just need to make sure you’ve worked enough insurable hours to qualify.

As for your job, the ESA offers protection. Provisions for medical leave ensure your position is held for you for up to 28 weeks, giving you the peace of mind to focus on your recovery.
